Explain the following in terms of gain or loss of oxygen with two examples each. (a) Oxidation (b) Reduction |
|
Answer» (a) Oxidation involves the gain of oxygen by a substance in a chemical reaction. For example, `2Zn(s) + O_(2)(g) overset("heat")to 2ZnO(s)` `2Ca(s) + O_(2)(g) overset("heat")to 2CaO(s)`. (b) Reduction involves the loss of oxygen from a substance in a chemical reaction. For example, `CuO(s) + H_(2)(g) overset("heat")to Cu(s) + H_(2)O (l)` `ZnO(s) + C(s) overset("heat")to Zn(s) + CO(g)` |
